APPARATUS FOR TREATING ORE Specification of Letters Patent. Patent d pia 10 1921 Application filed October 20, 1919. Serial No. 331,806.

To all whom it may concern.

Be it known that I, OSCAR J. ZIEGLER, a citizen of the United States, and resident of River Rouge, in the county of lVayne and ,3 ate of Michigan, have invented certain .or to be elevated step by step with relatively little agitation. Inasmuch as a much more efficient action of the 'cyanijd solution may be obtained by thoroughly agitating and aerating the pulp with the solution, it is the p in cipal object of the present invention to provide an arrangement for successively elevating the pulp and cyanid solution from one receiving receptacle of a series and dumping the same into another reeeptacleof the sameor an additional series.

A further object is to provide an apparatus of this character which is composed of one or more agitating and aerating units, which, in case several are used, may be combined in various relationships. For instance the several units can be positioned horizontally with respect to each other, or vertically, or at an incline, or in a combination of these various arrangements. Further more in view of such a feature an apparatus may be readily built up to accommodate any amount of ore pulp and readily increased in capacity when the amount of the latter increases.

Still another object is to provide an agitating and aerating unit for treating apparatus which can be easily varied as to capacity by changing the number of pulp and cyanid solution receiving receptacles.

With these general objects in'view, the in vention resides in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed.

In the accompanying drawings, Figure 1 represents a front elevational view of an aerating and agitating unit for ore treating apparatus.

Fig. 2 is a side elevational view, partly in section, of the unit shown in Fig. 1.

F 1g. is a diagrammatic view showing the association of several aerating and agitating un1ts to indicate the manner in whiclrthey may be associated, and 1 F g. l: is a sectional view through a pair of pulp and solution receiving receptacles showing one manner of associating the conveving and. agitating mechanism therewith.-

liefeiilng nowmore particularly to the drawings, it will be seen that each of the agitating and aerating units U which go to e up an ore treating apparatus is constructed in substantially the same manner and operated similarly, although each may be CllffGlGIlt as regards capacity and specific arrangement of parts. It will therefore be appreciated that the invention does not consist in the construction and arrangement of parts illustrated, but in any general arrangement embodying the same features and methods of operation.

The units U shown in Figs. 1- and 2 consist of a supporting frame comprising preferably angle metal corner bars 1, upper and lower transverse brace bars 2 and 3, and intermediate supporting bars at and 5, the latter'being horizontally and alternately disposed and vertically spaced. Each of the supporting bars 4- and 5 mounts'one or more bearings 6 in which sprocket shafts 7 are journaled, and in addition the supporting close proximity so that the opposite longitudinal edges thereof abut as indicated in Fig. 2, and in'the diagrammatic Fig. 3. Furthermore each series of receptacles thus formed is positioned substantially horizontally. The units illustrated are of comparatively small capacity, and therefore only a pair of receptacles is used in each of-the horizontal series with the exception of the lowermost which contains three receptacles. However, each series may contain any number of receptacles, and if de" sired, instead of having the series vertically mg sprockets are mounted on the shafts 7 journialed in the bearings on the supporting bars and are located within the receptacles 8, one being disposed adjacent each end of each of the receptacles, whereas the dumping sprockets are disposed over the receptacles 8.

As will be seen from Fig. 1, two sets of sprocket-s are employed, one being adjacent each end of the receptacles 8, and around each of the sets is trained an endless link belt or chain 12. The two link belts are connected by a plurality of relatively shallow buckets 13. In practice these buckets maybe of any appropriate length, but are preferably so spaced apart that there will be five in each foot of belt. The teeth of the sprockets 9, 10 and 11 engage in openings in the link belts 12 and cause the same to travel into and out of the several receptacles, the buckets 13 thus successively removing the ore pulp andcyanid solution from one receptacle and dumping it into an other. Thus in the structure illustrated in Figs. 1 and 2 the link belts 12 and their buckets 13 pass beneath the sprockets 9 and over the sprockets 10, the other sprockets 11 being arranged in suitable positions to guide the belts. The pulp and cyanid solution is very thoroughly agitated and aerated by being caused to drop a considerable distance from the buckets 13 as they pass over each pair of dumping sprockets and into the receptacle therebelow. This drop need not be very considerable in View of the fact that the pulp and solution is continu-,

are caused to discharge. In other words the vertical planes of these shafts of the sprockets 10 are disposed inwardly of the forward edges of the receptacles into which the buckets passing therearound are designed to dump, thus any pulp and solution removed by the buckets from one receptacle cannot be discharged back into the same receptacle, but must fall into the receptacle next in the series. However, in the form illustrated in Fig. at the vertical planes of the shafts of the dumping sprockets are directly over the abutting edges of the receptacles 8 so that a deflector plate 15 is secured to the abutting edges so that the pulp and cyanid solution cannot fall back into the same receptacle from which it has just been removed by the buckets 13.

From Fig. 3 it will be appreciated that various arrangements may be employed by transferring the pulp and solution from one of the units U to the other, for instance between the units a and b, the pulp and solution may flow by gravity from one of the receptacles 8 of the uppermost series'of the first unit through a chute or the like 16 to one of the receptacles ofzthe lowermost series of the other unit. In the unit 0 the pulp and cyanid solution is received from the unit I; in a supplemental receptacle 17 from which it is elevated to the first receiving receptacle of the lowermost series. The initial receiving arrangement of the other unit (Z is substantially the same, in the present case, to the unit 0.

With an ore treating apparatus of this character the loca-tion of the stamp mills is immaterial, as the several units may be assembled in practically any relationship. If space is limited the units may be positioned substantially vertically, whereas on the other hand if the plan-t may be spread out, or if climatic conditions prevent the association of the units in the form of a tower, they may be disposed substantially horizontally or in stepped relation.

I claim:

1. An ore treating apparatus unit com prising a pair of pulp and solution receptacles, one being an initial receiving receptacle and the other a secondary receiving receptacle, a guide disposed adjacent the initial receptacle, another guide located over the secondary receiving receptacle, an endless conveyer trained about the guides and removing the contents from the initial receptacle and dumping them into the secondary receiving receptacle, and intermediate guides for directing the conveyer about the other guides.

2. An oretreating apparatus unit comprising a pair of pulp and solution re'ceptacles, one being an initial receiving receptacle and the other a secondary receiving receptacle, and a second pair of pulp and solution receptacles disposed above the first pair of receptacles, one receptacle of said sec ond pair also being an initial receiving receptacle and the other a secondary receiving receptacle, a guide disposed adjacent each initial receptacle, another guide located over each secondary receiving receptacle, an endless conveyer trained about the guides and removing the contents from the initial receptacle of the first pair and dumping it into the secondary receiving receptacle of said first pair and then elevatin the receptacle contents from said seconc ary receiving receptacle of the first pair to the initial receiving receptacle ot the second pair, said conveyor removing the contents from the initial receptacle of the second pair and dumping it into the secondary receiving receptacle of said second pair of receptacles, and intermediate guides for directing the conveyer about the other guides.

3. An ore treating apparatus unit comprising a pair of pulp and solution receptacles, one being an initial receiving receptacle and the other a secondary receivin receptacle, a filling Wheel disposed in eadh of the receptacles, a dumping Wheel disposed above the receptacles, an endless conveyer disposed below the filling W eels and above the dumping Wheel Wherebyto remove the contents from the initial receiving receptacle and dumping it into the secondary receiving receptacle, and intermediate guide Wheels for directing the conveyer about the other Wheels.

4. An ore treating apparatus unit comprising a pair of pulp and solution receptacles, one being an initial receiving receptacle and the other a secondary receiving receptacle, a filling Wheel disposed in each of the receptacles, a dumping Wheel disposed above the receptacles, the center of the dumping Wheel being in a vertical plane Within the sides of the secondary receiving receptacle, and an endless conveyer disposed below the filling Wheels and above the dumping Wheel whereby to remove the contents from the initial receiving receptacle and dumping it into the secondary receiving receptacle, and intermediate guide Wheels for directing the conveyer about the other Wheels.

In testimony that I claim the foregoing I have hereunto set my hand at River Rouge in the county of Wayne and State of Michigan.
